What kind of fabric is Sea Island Cotton? Characteristics of Sea Island cotton, native to South America, Central America and the Caribbean. Because it was once widely distributed on the southeastern coast of the United States and nearby islands, it is called sea island cotton. Sea-island cotton was first widely cultivated in Chile and Ecuador in South America, and was later introduced to North America, Egypt, Sudan in Africa, and some countries in Asia.
The world-famous Egyptian cotton originally belongs to the island cotton species. After a long period of selection and domestication in Egypt, it has excellent quality, high yield, and the largest planting area. At present, the main producing countries of long-staple cotton are: Egypt, Sudan, the Soviet Union, the United States, Peru, Morocco, etc. In modern times, there are many varieties of island cotton cultivated in various countries around the world, including Egypt’s “Giza 45” and “Giza 70”; Sudan’s “Vais” and “Barakat”; and the Soviet Union’s “6465 Fu” and “9647 Yi”. “; there are also varieties such as “Pima” from the United States, Peru and Morocco. China has a long history of producing long-staple cotton, which is a species similar to sea-island cotton. This cotton species was originally distributed in Kaiyuan, Yunnan, Hainan Island, Guangdong, and southern Fujian. Most of them are perennial sea island cotton. In the 1950s, the Soviet Union’s annual sea island cotton was first successfully introduced in Xinjiang. Later, after many cotton species changes, “New Sponge” and “Junhai Cotton” are now widely promoted in Xinjiang.
“No. 1” and other varieties, the fiber quality has met the requirements of the textile industry.
Characteristics
The characteristics of sea-island cotton fiber are: bright color, long length, generally 33~39 mm, the longest can reach 64 mm; the fineness is 7000~8500 meters/g, the width is 15~16 microns; the strength is high, 4~5 gf/root, the breaking length is 33~40 kilometers; there are many turns , 80-120 pieces/cm. In textile production, it can be divided into two types according to its different length and economic value: extra-long staple cotton with a fiber length of more than 35 mm and medium-length cotton with a fiber length of 33-35 mm. Staple cotton. Higher-grade extra-long staple cotton was originally the main raw material for spinning large tire cords. It has been gradually replaced by chemical fibers. Now it is used to spin No. 7.5 to No. 4 (80 to 120 British count) combed yarn and combed pagoda. Raw materials for high-end yarns such as threads. Higher-grade medium-long staple cotton can be used to spin medium-sized tire cord, No. 10 to 7.5 (60 to 80 British count) combed yarn, combed sewing thread and other yarns. In recent years, There are some hybrid varieties with Sea Island cotton as the male parent and Upland cotton as the female parent. The fibers are longer, but the fineness and strength cannot reach the specifications of Sea Island cotton. They are commonly known as upland long-staple cotton.
